Fostering university-industry collaborations through university teaching
2019
Unversity-industry links and their impact on innovation processes have been widely acknowledged. However, previous studies have mainly examined university-industry knowledge transfer activities from the perspective of the research and third stream missions. This paper goes a step further, analysing such processes from the perspective of the university’s teaching mission. More specifically, it explores how educational crowdsourcing platforms help bring universities and industry together to develop joint activities in undergraduate and graduate programmes. Nine platforms with different business models were examined. A qualitative exploratory approach was adopted to manually collect and analys…
Hemispheric differences in specificity effects in talker identification
2010
In the visual domain, Marsolek and colleagues (1999, 2008) have found support for two dissociable and parallel neural subsystems underlying object and shape recognition: an abstract-category subsystem that operates more effectively in the left cerebral hemisphere (LH), and a specific-exemplar subsystem that operates more effectively in the right cerebral hemisphere (RH). Evidence of this asymmetry has been observed in priming specificity for linguistic (words, pseudoword forms) and nonlinguistic (objects) stimuli. In the auditory domain, the authors previously found hemispheric asymmetries in priming effects for linguistic (spoken words) and nonlinguistic (environmental sounds) stimuli. In …
Initial results of NEXT-DEMO, a large-scale prototype of the NEXT-100 experiment
2013
NEXT-DEMO is a large-scale prototype of the NEXT-100 detector, an electroluminescent time projection chamber that will search for the neutrinoless double beta decay of Xe-136 using 100-150 kg of enriched xenon gas. NEXT-DEMO was built to prove the expected performance of NEXT-100, namely, energy resolution better than 1% FWHM at 2.5MeV and event topological reconstruction. In this paper we describe the prototype and its initial results. A resolution of 1.75% FWHM at 511 keV (which extrapolates to 0.8% FWHM at 2.5 MeV) was obtained at 10 bar pressure using a gamma-ray calibration source. Also, a basic study of the event topology along the longitudinal coordinate is presented, proving that it…
El modelo de Ausubel en la didáctica de la física : una aproximanción experimental al proceso de E/A de contenidos que presentan constructos poco ela…
1993
Resumen basado en el de la publicación Resumen en inglés Se muestran los resultados de una investigación sobre educación física sobre «Magnetismo» en la escuela secundaria. Se investiga un enfoque constructivista para el diseño instruccional basado en el modelo de Ausubel en el tratamiento de temas en el cual los alumnos tienen representaciones conceptuales pobres y marcos alternativos. Se muestran los primeros resultados con respecto al aprendizaje inmediato y duradero. ESP
Wittgenstein a la luz de Aristóteles
2008
This paper compares the way Aristotle explains how one body gets alive or the way one mind manages to understand, with the way Wittgenstein discusses some questions as how is it possible to get meaning from the sign, or to follow a rule. The paper’s goal is not to establish a real influence of Aristotle on Wittgenstein, but to explore some logical aspects of their explanation patterns, with the aim of clarifying several notions of Wittgenstein’s later philosophy. El artículo compara el modo como Aristóteles explica que un cuerpo llegue a vivir o que una mente llegue a entender, con el esquema explicativo que emplea Wittgenstein para dar cuenta de problemas como éstos: ¿qué hace posible que …
There is no puzzle about change
2009
This paper argues against the common practice of presenting perdurantism, endurantism, and other views about persistence and time as solutions to an alleged puzzle about change. Different recent attempts to generate a puzzle about change are examined and found unsuccessful. This does not mean, however, that the relevant views about persistence and time are not well motivated, but rather that their interest and purpose is independent of their suitability for solving the alleged puzzle.
The Principle of Inferential Justification, Scepticism, and Causal Beliefs
2000
There is an argumentative route that begins with a platitude like: The Principle of Inferential Justification (PIJ): 'To be justified in believing one proposition P on the basis of another proposition E, one must be (1) justified in believing E, (2) justified in believing that E makes probable P' and ends up by challenging our capacity to justifiedly believing propositions concerning physical objects and past events. This is, at least, what Richard Fumerton claims, but, like Christopher Hookway, I doubt that there is such a route. In the coming pages, I seek to show how Hookway's challenge may find additional motivation in a reflection on the content of a certain kind of belief, namely: bel…
A Challenge to Boghossian's Incompatibilist Argument
1998
The paradox arises as we realize that (3) is clearly not knowable a priori, but (1) and (2) are. (2) holds 'a priori' because, according to Boghossian, it "just is the view that I have called the doctrine of privileged self-knowledge" (p. 202). The core of the paper is devoted, though, to argue that an externalist (i.e., someone who holds the view that "... facts external to a thinker's skin are relevant to the individuation of (certain of) his mental contents" (p. 199). is bound to concede that (1) is knowable 'a priori'. It would follow that, contrary to intuition, (3) can be known a priori since is the conclusion of an inference that relies on two premises that are, in
Operation and first results of the NEXT-DEMO prototype using a silicon photomultiplier tracking array
2013
NEXT-DEMO is a high-pressure xenon gas TPC which acts as a technological test-bed and demonstrator for the NEXT-100 neutrinoless double beta decay experiment. In its current configuration the apparatus fully implements the NEXT-100 design concept. This is an asymmetric TPC, with an energy plane made of photomultipliers and a tracking plane made of silicon photomultipliers (SiPM) coated with TPB. The detector in this new configuration has been used to reconstruct the characteristic signature of electrons in dense gas, demonstrating the ability to identify the MIP and "blob" regions. Moreover, the SiPM tracking plane allows for the definition of a large fiducial region in which an excellent e…
Estudi exploratori comparatiu del coneixement didàctic del contingut sobre piles galvàniques de professors de secundària en exercici i en formació
2021
En este estudio exploratorio se evalúa el conocimiento didáctico del contenido (CDC) sobre pilas galvánicas de profesores de secundaria en formación y en ejercicio. Además, este conocimiento se ha relacionado con los enfoques de enseñanza que prefieren. Para este propósito, se ha adaptado el instrumento CoRe de Loughran, Mulhall y Berry (2004) considerando dos situaciones: pila Daniell y pila voltaica simple. La muestra se compuso de 25 profesores en formación y de 15 profesores en ejercicio. El análisis de los resultados obtenidos hasta ahora sugiere que, en primer lugar, el CDC de los profesores de secundaria sobre pilas galvánicas no es el deseable; en segundo lugar, el CDC de los profes…
